HVAC - Airconditioner Chiller Tones

I have an Air--Vac System to Vacuum out my airconditionon system in my van. It has a standard 1/8 " pipe copper male fitting I think to receive the vacuum and needs a M12-1.75 male Flare fitting to attach the hose to that hooks up to the guages. Do you have a fitting that will work for that configuration? I will also need the price I am on disability and most of it is gone this month.
